The Hedera Hashgraph Platform will start with a small number of nodes during the testing phase. Then it will expand to have nodes run by all the council members. It will later expand to include other participants. Later, we anticipate this will become available to anyone who wants to host a node (and meets basic requirements for bandwidth, CPU, and storage). We expect to eventually have millions of nodes around the world, run by ordinary people, many of whom might choose to remain anonymous.
